WP Pneumatic Spool Valves

The Bosch Rexroth WP Pneumatic Spool Valves are direct-operated directional spool valves designed to control the flow of hydraulic fluid in high-performance systems. Available in configurations like 4/3, 4/2, or 3/2-way versions, these valves are key components for fluid logic control. The "WP" designation means the valve works by using pneumatic actuation, which requires an external air control pressure to shift the main control spool. This mechanical shifting of the spool is the function that controls the start, stop, and precise direction of the fluid flow. The valves are designed to handle demanding applications, with larger units rated for a high maximum operating pressure of 350 bar and a maximum flow of 160 l/min.
